在 docker-compose 中设置 postgres 和应用程序服务后，无法访问 Postgres
After setting up postgres and app service in docker-compose the Postgres is not reachable
我正在尝试使用 Postgres 作为数据库为 Hanami 网络应用程序设置多服务 docker 环境。我正在关注 Docker 和其他资源来这样做。我目前有两项服务：postgres 和 app。我平移为 nginx 添加一个单独的。在我 运行 docker-compose up 之后，一切“似乎”都正常，但是在我访问本地浏览器中的 url 之后，我收到了关于 Postgres 的错误。

我已经比较了通过 docker 宁 运行 或从我的应用程序根目录启动普通服务器时的终端输出。
Docker 输出：
web_1 | * Listening on http://0.0.0.0:2300
本地计算机上的应用程序服务器输出：
* Listening on http://127.0.0.1:2300
* Listening on http://[::1]:2300
这可能是问题所在吗？
不要将您的连接称为 localhost
Cannot assign requested address Is the server running on host "localhost"
从您的应用引用容器名称db
你在 docker 内部工作，它有自己的网络，所以当你使用 localhost 时，你引用的是你的应用程序不在 运行 上的主机网络
